Abstract :
Using simple and cost-effective tags, passive RFID systems offer a promising aid for identifying and localizing objects and users in indoor environments. Although systems based on radio frequencies usually suffer from multi-path interference and signal scattering, we show that the characteristics of such interference and scattering can be analyzed with passive RFID. We present and analyze measurements of received signal strength (RSS) conducted in an indoor environment using a passive bistatic RFID-System. In order to characterize the influence of human presence on RSS, measurements were conducted for different user locations and orientations in an indoor deployment area. Finally, an analytical approximation of the relation between user location and RSS is presented in accordance to our measurement results.
